Product description

Glyceryl Caprylate/Caprate is a multifunctional ester of glycerin and medium fatty acids(C8/C10 - caprylic/capric), derived from vegetable oils.
Technologically, it is produced by esterification (reaction of glycerin with fatty acids) to form a lipophilic component with partially surfactant behaviour. In practice, it functions as a light emollient, a co-emulsifier and also as a multifunctional "preservative booster" (promoting microbial stability in combination with a preservative system).
Due to its structure, it improves spreadability, reduces oily range and helps to stabilize texture - especially in emulsions and anhydrous products. It does not contain PEG or EO/PO and is often sought after in "clean" formulations.

Key benefits

• Multifunctional emollient - softens skin, improves slip and reduces "heavy" greasy feel.
• Co-emulsifier - promotes emulsion stability and contributes to a creamier, more compact texture.
• Preservative booster - promotes microbial stability of the formulation (especially when combined with a preservative and appropriate pH).
• Sensory enhancement - helps to "lighten" the oil phase and improve spreadability even with higher oil/butter ratios.
• Also suitable for delicate systems - often used in products where the aim is to minimise irritants whilst maintaining stability.

Suitable for products such as

• Creams and body lotions (both O/W and W/O) - stability, texture, sensory.
• Facial serums and emulsion fluids - lighter touch, improved spreadability.
• Cleansing and washing products (shower gels, facial gels, shampoos) - promoting softness and comfort after washing.
• Deodorants (cream and solid) - improve spreading and promote formulation stability.
• Waterless balms (lip balms, body balms, make-up balms) - slip, "dry touch" effect, consistency fine-tuning.

Use in formulation

• Soluble in: oils and oil phase; insoluble in water - incorporated into aqueous systems via emulsification or suitable solubilization system.
• Miscible with: vegetable oils, esters, butters and most lipophilic actives; in emulsions, typically added to the oil phase.
• Compatible with: both O/W and W/O emulsifiers (as a co-emulsifier) and with common preservative systems; the "booster" effect depends on pH, aqueous activity and overall formulation composition.
• Dosage (indicative): most commonly 0,5-5 % depending on product type and objective (sensory, co-emulsification, preservation support).
• pH compatibility (indicative): often reported stability in the pH range 4,5-7 (it is recommended to verify in a specific formulation and with a specific preservation system).
• Technological tip: for emulsions, you can dissolve it in the oil phase (with gentle heating if necessary) or incorporate it cold into an already homogeneous oil mixture; then fine-tune the viscosity and stability of the emulsion.

Safety and storage

• For cosmetic use; avoid contact with eyes and mucous membranes.
• Observe normal hygiene principles when working and use clean tools to avoid contamination.
• Store in a tightly closed container, in a dry place, out of direct sunlight and away from heat sources.
• For sensitive skin, we recommend testing the final product on a small area (especially for products for children or very reactive skin).

Physical properties

• Appearance: white to creamy thick paste (at temperatures around room temperature).
• HLB (indicative): approximately 4.8 - more lipophilic in nature, particularly suitable for the oil phase and as a co-emulsifier.
• Behaviour in formulations: influences viscosity and "skin feel", often reduces oily range and improves spreadability.
